Protocol 2

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

Start around October 13, 2026 for a May 3 last frost.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

  2. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C

    A further 13% germinated after the shift to 70.

Steps after step 1 run on after germination.

about 3 months from start to sowing. Then 84 days to germinate.

60% germination in 35–84 days.

Sowing straight at 70 is both faster and complete.
